A clash between souls. The very energy that makes up who they are, clashing in a realm where the laws of the world are no longer applicable.
It's not just the strength of the soul that matters. It's the soul's will to live on. The soul's importance for the future of the world. The soul's grit and determination, as well as its capacity for change.
The universe is an unstable thing. Large stars die in massive supernova explosions, wiping out anything within its vicinity. They are a destructive force. But they also provide light to nearby organisms.
So, to control the power of one of the stars, the soul must be strong. It must be willing to destroy when the time comes. They must be willing to hurt those around it. But they can also provide light in the darkness. Some who are chosen by these stars are meant to lead, to provide growth and change for their people.
